    Yes.

    You have to make sure you've got power everywhere you're supposed to.

  7. Any newer players in the 9-11" horizontal bandsaw field?

    Cosen is a good saw, Taiwanese made. You can get the Cosen 10x16 for around $4500.

    I've had one (from new) for a decade now, with no issues.

    And it gets used a lot!
